Secondary structures are alpha helices and beta sheets. The helices and sheets provide stability to the compound as a whole. The alpha helices are represented with pink arrows and the beta strands are represented with yellow arrows. This molecule has approximately eight alpha helices and four beta sheets. Alpha helices have a cylinder-like structure with a parallel formation. This representation shows these key features of alpha helices. Here, you can see the parallel formation within the cylinder structure. The parallel alpha helices are held in its cylinder structure by hydrogen bonds. Beta sheets are often anti-parallel, which can be seen in this representation. The folding of a protein, alpha helices and beta sheets, are what gives the compound its function. When there is a change in protein folding, the function will change. As previously stated, the study discovered ACC(2’)-Ic to have a GNAT fold, and the GNAT family are a group of enzymes capable of acetylation.
